To all whom "it may concern: 1 g

Be it known that I, HARRY C. GAMMETER, a citizen of the United States,residing at Bratenahl, in the county of Cuyahoga and State of Ohio, haveinvented a oer-tam new and useful Improvement in Rot'atable'Type- 7Holding Mechanism, of Which-the following is a full, clear, and exactdescription, reference being had to the accompanying {drawings. My No.

setting and distributing mechanism, wherein type may be transferredmechanically froma storage drum to a printing drum,

and when on thevlatter, printed by'rotationof the printing drum incooperation with the rotary, platen. Among the features; shown in thatapplication are mechanisn i holding}- for continuously rotating thetfy'p printing drumand mechanism or" feed ng: it step by step withreference to a recess through which type may be supplied, and.

mechanism for holding the drum against displacement, thusl' rovidingforconvenient loading or unloading of the drum. The presentapplicationrelates-to these features.

The invention hereof includes a rotatabledrum-like structure havin'means for holding longitudinal rows '0 type, combined withmeans forgiving such-device partial rotations step by step, corresponding to the'distancebetween type holders to bring any ings hereof and is,hereinafter more fully described and claimed. These draw ngs are t inthe nature of extracts from the parent application referred to.

In the drawings, Flgure bodying my invention; Fig. 2 is an enlargedvfrzagmentary elevation of the holding device, the same being on atransverse plane indicated by the line 2 of Fig. 1;'Fi'g. 3 is a similarview in vertical section. through the application N0'.J1j96,840-t-renewed as 2'97;447 "filed March/Z, 19Ol, of -which this applicationis a divisionfishows a' rotary" printing mechanism combine'd witha typel'is a front ele-' 'vation of'a rotary'typeholding device emend member ofthe frame, as indicated by the line marked 3. in Fig. 1; Fig. 4 is a.sub-- stan-tially plan view of the holding device shown in Figs. 1, 2and 3, this view looking toward theaxis of the drum instead of directly'downward; Fig. 5- is a transverse, vertical section of the machine shownin Fig. 1; Fig.6 is a perspective view of one of the type-holding railsand a type'thereon, which may be employedin this mechanism; Fig. 7 is afragmentary plan of the top portionof the left handendplate showing thetype guide carried thereby.

As shown in the drawings, the "machine consists' ofa suitable baselO and12, Mounted in these uprights is a shaft 13. On this shaft is adrum-like member adaptedto hold parallel lines of ;type. As shown in.the drawings, this gdrum-like member has end plates or disks Q14: and'l5rigid on the shaft. Connecting jthese disks. is a partially cylindricalformries of parallel longitudinal rails 17 carried-"thereby. The railsare shown as rigidly mounted on thesupport and thesupportas rigidlyconnected to the disks. The rails are provided with overhanging edges 18whereby they are adapted to hold lines of shown, the type, designated 20inFi'gjfi, has a groove from its bottom. upwardly, enlarging interiorly,and this type straddles nient thereon by the enlargement 18.

In the form the rail, being held againstoutward movetype, accordingly, occupy channelsbetween ever, that-,vi-nplace of this, if desi :ed,;-,the I construction shown in my prior-Patent tire type stands between adjacent-rails,i the In installing thein a page form onv I PatentedJan, 23,1912. 1 Original application filedMarch 7, 1904, Serial No. 19c,s4o;' ,-,mn w a; January 23,1900, SerialNo.

the'frame of typeholder. To hold the type in presentation-with anyholder which may be brought to transferring position,- I have shownhere= in the means shown in my parent; applica-- tion referred to.- Thisappears more particularly in Fig. 7 and consists of'an'np wardly facing,partly circular, recess24'inthe upper end of the frame-member forstandard 11, this recess being partly bounded by the ribs 25. In thisrecessis a'mov-q able cylindrical head or typeholder 26, which has on anotch 27 which is occupied-by a block 28. The notch .is shownas'-'having four arms and the blockas being made in, the form of a Greekcrossf Between one'of the lateral arms of the block and the side of thehead is a space large enough for a single type, as shown-at 29inFig. 7 1When a type 1s in such position andthe block is moved against it, as itmay be by. any suitable means, the type is shoved-onto the typeholder17, shoving in advance thereof the type already thereon, indicated by20. 'From this construction it follows that when any of the typeholdersOIIthG drum-like member are brought into the active position, type maybe shovedthereonto from the holder 1n the recess-toassemble type ormovement in the. reverse direction may distribute type.

My parent application shows means "for givinglthe head 26 'halfrotations back and forth and formovin'g the block in the head, sothatthe typemay'berecei'ved on'the left a hand side of the memberll andswing about through a half circle and shoved out laterally on the righthand side. For the present purpose, however, it is believed to besufli'cient to showthe-movable typeholder or head in the recess andthemovabl'e member which shoves'the'type out of such head onto thealine'd typeholder. The rotatable head and its jo'per'atin mechanism iscovered in the'parent application referred to.

In order-to hold the drum-like member in position with reference tothe'recess 24; and to feed it step by step, I provide the foll'owingmechanism. Mounted on'the right hand end of the disk is a member havingteeth 30. These'teeth' correspond in their spacing to the typeholders,asshown, there is one tooth for .eachrail. Coacting with these teeth,andforming 'means for rotating the drum-like member step by st'epfis adriving device shown as a three-tooth" pinion 31' mounted on a shaft.32, which has on its outer end a knurled head 33'. This shaft is shownas mounted i'na pair ofwseparated cars 34 of the frame member 12 andbetween theseears the shaft istriangular-in cross section, 'as shown at35, Fig. stand on this :tri-angtilar portion bears a' fl'at spring37.

This spring serves to hold theshaftagainst accidental displacement andtends tobring it to definite'posit ion while allowing it to be rotated.Theteeth-of the .pinioI'1 31 are .6 s placed that, normally, they areall out of the pat-h of the teeth so that the drumlike member mayberotated independently of this: pinion d'riverr. When the driver isrotated, however, one of its teeth, shoving against one of theteeth'30,flfeedsthe .drum memberiforwardu. To prevent-accldentaldisplacement oft-he drum :1 provide a spring brake 40,shown as ale'af"spring;"carryingv at its" free enda roller 46 adapted-to engage theteeth 30.-andbear between adj acjentteeth; Theisprings etfland' 37; may,in reality, b eopposite extensions ofa single spring, which I is shownassecured teat-he frame; member 12 by screws 41.. This device'inakes-aspring brakeon the rotation of the drum so thatthe turning of theknurled head 33 doe'snot spin 1 the drum, but feeds it'gradually forwardto present successive typeholders to the active position. Togive thedrum a more continuous rotation, orport-ion of it, I provide a suitablehandle 50 connected with the shaft 13. I This handle is shown as a cranka 11 having on its shaft agear 51 meshing with a gear 52 on the shaft13. By this means the drum may be rotated in either direction any porton of a rotation," or contmuousrotations,'as desired; "-To enable thebrake l0 to be thrownout of action, fora less retarded 1 rotationjby thehandle 50 or otherwisef' l' provide a'rock-shaft 42,- journaled'in anear 43 rising from the frame member 12. This rock shaft has a flattenedportion' JAst-anding-beneath the spring and has on'its' I other end ahandle 45. Thep-ressure of the spring 40 normally holds the 'rock'shaft42 in the position shown, but whenever desired, the 'same may be turnedby the handle to force the spring outwardly, relieving the "f brake. I

Figs. 1 and '5 show *a-rotary platen mounted parallel with" the drunrandhaving a soft exterioradapted' to cotiperate with'the type on the drum.This platen is shown as provided with agear (ll-meshing with the gearteeth 30. These latter teeth,

therefore, have the double function ofcooperating with.the driver tolocate the drum and coiip erating' with the platen gear to drive theplaten. In this later action, the

drum andp'laten concurrently rotated by the crank 50, form-arotaryprintingcouple' adapted to print paperbetween them. 1 For purposesof supplying ink-for suchimprint,

Imay provide a pair of'spools mounted between the drum disks l t and andv 'adapted'to carry'thewmmd-up "ends of an inking ribbon ,passingintermediatelv across is the type,after the manner of my prior 'pat entreferred to.
